Multi Layer AR Thin Film Optical Coating Anti-Reflective Coating

Overview:

Anti-reflective coatings are used on the surfaces of the substrates to reduce the amount of light reflected from each surface and improves transmission, which is important in low-light applications, and prevents the undesirable effects like ghost images particularly associated with multiple reflections. 

Normally, the more layers in the anti-reflective coating, the more reflections are neutralized. And depending on the design, each anti-reflective coated optic will reflect a certain color. Usually, it does not affect the performance.

Our advanced thin film coating technology allows us to produce hard anti-reflective coating to resist from scratch, waterproof and perform well in harsh enviroment. 

Despite of the following most commonly used anti-reflection coating, we also support special design like triple band anti-reflective coating of  589nm, 1064nm&1319nm.
